Changed lockdir to /var/lock/masqmail; Create lockdir and piddir on startup.
Moved the lockdir out of the spool dir. (When /var/lock is a ramdisk
we do well to have the lock files there.) Added the new configure option
--with-lockdir to change that location. Nontheless, if we run_as_user,
then lock files are always stored in the spool dir directly.
Instead of installing the lockdir and piddir at installation time, we
create them on startup time now if they are missing. This is necessary
if lockdir or piddir are a tmpfs.

226 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
227 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
228 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
229 #
230 # Of course, Automake must honor this variable whenever it calls a
231 # tool from the auxiliary directory. The problem is that $srcdir (and
232 # therefore $ac_aux_dir as well) can be either absolute or relative,
233 # depending on how configure is run. This is pretty annoying, since
234 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
235 # source directory, any form will work fine, but in subdirectories a
236 # relative path needs to be adjusted first.
237 #
238 # $ac_aux_dir/missing
239 # fails when called from a subdirectory if $ac_aux_dir is relative
240 # $top_srcdir/$ac_aux_dir/missing
241 # fails if $ac_aux_dir is absolute,
242 # fails when called from a subdirectory in a VPATH build with
243 # a relative $ac_aux_dir
244 #
245 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
246 # are both prefixed by $srcdir. In an in-source build this is usually
247 # harmless because $srcdir is `.', but things will broke when you
248 # start a VPATH build or use an absolute $srcdir.
249 #
250 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
251 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
252 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
253 # and then we would define $MISSING as
254 # MISSING="\${SHELL} $am_aux_dir/missing"
255 # This will work as long as MISSING is not called from configure, because
256 # unfortunately $(top_srcdir) has no meaning in configure.
257 # However there are other variables, like CC, which are often used in
258 # configure, and could therefore not use this "fixed" $ac_aux_dir.
259 #
260 # Another solution, used here, is to always expand $ac_aux_dir to an
261 # absolute PATH. The drawback is that using absolute paths prevent a
